Every time you present your results to a person in a managerial position or who does not have expertise in the technical details and processes you followed to get your results

Explanation:

When it comes to software projects documentation, you generally have to build a report that will be read by different people. These people come from different backgrounds and know the project to a different extent. For this reason, the project should contain sections that facilitate the understanding of the reader.

In general, the first section of a project report is an executive summary. The executive summary is a concise description of the project, starting from the problem context and description, including the results, conclusions, and recommendations.

It should be no more that one page long and it should be written in a general language so whoever reads it understands what is your project about.

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// function that return the first occurrence of item

int fun(int a[],int item,int n)

{

   for(int y=0;y<n;y++)

{// find first occurance

   if(a[y]==item)

   // return index

   return y;

}

}

// main function

int main()

{

// variables

int n,item;

// array that holds 256 number only

int a[256];

cout<<"enter the value of n:";

//read the value of n

cin>>n;

// if n is greater than 256, it will again ask for input

while(n>256)

{

   cout<<"value of n should be less than 256:"<<endl;

   cout<<"enter value of n again:";

   cin>>n;

}

// read n numbers

cout<<"enter "<<n<<" numbers:";

for(int x=0;x<n;x++)

{

   cin>>a[x];

}

// read item to be searched

cout<<"enter the number to be searched:";

cin>>item;

// calling the function and print the index

cout<<"item found at index "<<fun(a,item,n)<<endl;

}

Explanation:

Declare a variable "n" and create an array of size 256.Then read the value of "n". If n is greater than 256 then it will again ask user to enter a number less than 256.Then it will read "n" numbers from user and store them into array.Then it will read item to be searched and call the function with parameter array, item and n. function will find the first occurrence of the item and return its index.

Output:

enter the value of n:280

value of n should be less than 256:

enter value of n again:7

enter 7 numbers:12 4 7 9 7 6 21

enter the number to be searched:7

item found at index 2

Answer: (C) Highlighting

Explanation:

Highlighting is the process in which we can use the different effects of the color for highlight the background and also used for emphasize the text. Highlight is very useful in highlighting the important line, text and any kind of special word.

It is mostly used for draw attention towards the important sentence in the given whole page or paragraph by highlighting some important line or words.

On the other hand, all the other options are incorrect as they does not involve in the color effect for emphasize the text.

Therefore, (C) is correct option.

The above statement declares an array of size 6 which can store elements of type string or word. Then I have initialized the first and second elements with the word humming and the rest of the places in the arrays are uninitialized.

You have to include the header file string so that this array could work otherwise it will not.

Answer: True

Explanation:

 Yes, the given statement true that the if the component and any type of the services are critical then, there is higher level of the availability require. The critical component and services basically require more steps of implementation and also people so that they can verify each step of component and services that are implemented.

The high availability is basically the ability of the component system that are operated continuously to get the desired product availability. It also increase the efficiency of the desired component and services.

Final answer:

True, critically important services require a higher level of availability. Industries with higher stakes like airlines and healthcare invest more in reliability and security to avoid significant disruptions and maintain operations, reflecting the balance between higher costs and the need for constant system availability.

Explanation:

The statement 'The more critical a component or service, the higher the level of availability required' is indeed true. In the context of business and Information Technology (IT), critical functions demand higher availability because any downtime can result in significant disruptions, financial loss, and damage to reputation.

For instance, industries like airlines and healthcare require a near-constant uptime due to the high stakes involved in their operations. An IT breakdown in these fields could have dire consequences, not just in terms of revenue but also in terms of human safety. Therefore, these sectors invest heavily to ensure reliability and security of their services. Conversely, in organizations where IT is less critical, there may be less willingness to invest in such high levels of preparedness. This trade-off is sometimes referred to as the balance between reliability and cost. The cost of achieving high availability is justified in critical systems, while for less critical systems, a lower level of redundancy and availability may be deemed acceptable due to the lower associated risks and costs.

Final answer:

To calculate the distance fallen by the watermelon, use the formula d = 0.5 * g * t^2. Ask the user for the number of seconds the watermelon falls and the height of the bridge. Use a loop to calculate the distance fallen for each second and check if the total distance is valid.

Explanation:

To calculate the distance fallen by the watermelon, we can use the formula d = 0.5 * g * t^2, where g is the acceleration due to gravity and t is the time in seconds. The user will be asked to input the number of seconds that the watermelon falls and the height h of the bridge above the water. We can then use a loop to calculate the distance fallen for each second from t = 0 until the value of t input by the user. If the total distance fallen is greater than the height of the bridge, the program should display a message indicating that the distance fallen is not valid. Here is an example code in Python:

Answer:

True

Explanation:

An object is used as a central concept in OOP. It contains data (state it represents) and behaviors (the message) that has a meaning in your software application. Most programmers like using object-oriented programming languages because of these objects it carries. These objects make it easier to build solutions with complete functionalities effectively. It represents the properties which are the data state and a method which is what it can do. A customer’s object data or property, for instance, is every key detail of the customer while the method is what this object can do with the data.

Answer: Compiler

Explanation:

 The exception classes are basically occur during the compilation of the program in the system. The exception is the event which disrupt the flow of the instruction.

It basically provide a way to transfer the control in the one part of the program to another program. The exception class is also known as run-time exception that basically indicate the condition in the class application.

All the other options are not in the form of packages in the exception class. Therefore, compiler is the correct option.

Answer: Doxing

Explanation: Doxing which is also referred as doxxing is defined as the revealing or publishing of the private records or information to the public.It is considered as the illegal practice which is base on the the internet service.The publicizing of the private data or confidential information is punishable offence.

Other options are incorrect because filtering is the elimination of the not required content, spamming is the activity of sending undesired bulk messages and hacking is the attacking of the system using false means to corrupt and steal data.Thus the correct option is doxing.

class Student

{

public:

string name;

private:

int age;

public:

int accessor()   //accessor

{

   return age;

}

void mutator(int value)   //mutator function.

{

   age=value;

   return;

}

}

Explanation:

The above written statement creates a pointer of name p.Then the address of variable x is stored in the pointer p and it is done by using the & referencing operator.By doing this the address of the variable x is stored in pointer p.

In the next question two public functions are created with the names accessor and mutator respectively.Accessor function are used to access private values in the class and the Mutators are used to set the prviate values.That is what the accessor and mutator function is doing in the class.

Answer:

// here is code in java.

public class NAMES

{

// main method

public static void main(String[] args)

{

int n=4;

// print the upper half

for(int a=1;a<=n;a++)

{

for(int b=1;b<=n-a;b++)

{

// print the spaces

System.out.print(" ");

}

// print the * of upper half

for(int x=1;x<=a*2-1;x++)

{

// print the *

System.out.print("*");

}

// print newline

System.out.println();

}

// print the lower half

for(int y=n-1;y>0;y--)

{

for(int z=1;z<=n-y;z++)

{

// print the spaces

System.out.print(" ");

}

for(int m=1;m<=y*2-1;m++)

{

// print the *

System.out.print("*");

}

// print newline

System.out.println();

}

}

}

Explanation:

Declare a variable "n" and initialize it with 4. First print the spaces (" ") of the upper half with the help of nested for loop.Then print the "*" of the upper half with for loop. Similarly print the lower half in revers order. This will print the required shape.

Answer:

for ratio 1:4

height for antenna 1 = 42.36

and height for antenna 2 =169.46

Explanation:

given data

distance d = 60km

height h1 = 4 h2

to find out

find the appropriate heights of these two antennas

solution

we know here that distance between 2 antennas  in LOS ( line of sight ) is express as

[tex]d = 3.57\sqrt{kh}[/tex]   ......................1

here d is distance and k is curvature of earth i.e 4/3  and h is height

we know height is 1:4 so total height is 5 part to get ratio

put value in equation 1

[tex]60 = 3.57\sqrt{\frac{4}{3} h}[/tex]  

solve it we get

h = 211.83

so for ration divide by 5

[tex]\frac{211.83}{5}[/tex]

= 42.36

so for ratio 1:4

so height for antenna 1 = 42.36

and height for antenna 2 = 4 × 42.36 = 169.46

Answer:

Unique.

Explanation:

Unique is supported by a primary key because of primary key we can uniquely identify the tuple so the attribute which has been set as primary key must contain values that are unique and these values cannot be null.These values should not be changeable over time and updateable because there is a chance if these values are manipulated a copy of it may be present in that attribute.So the primary key won't be able to uniquely identify the tuple.

Answer: Random-access files are those file types which have the capability of being accessed anytime directly without the requirement of any other support or file.The reading and writing of data can be done from anywhere and any point of time.

Sequential-access files are those files which can be accessed only in sequential manner for the writing and reading purpose.The sequence followed is from beginning to end of file.

Performance-oriented situation requires those files in working that can perform with the superior ability to carry out the job and can be assessed easily as per demand.Thus, these features are performed by random access file as compared with sequential-access files.So, random -access files are more preferred .
